At the first end 106, the housing 102 includes a top perimeter edge 107 and two axially extending walls 151. The walls 151 extend above the top perimeter edge 107 and each wall 151 is positioned substantially opposite each other relative to the longitudinal axis 118. Each wall 151 forms a groove 150 configured to receive a handle assembly 122 of the cover 120 as described further below.
Referring to
Each end 152 of the handle assembly 122 is received within a groove 150 formed in the housing 102. Each of the outer handle members 142 includes a latch 144 that engages with a retainer 146 of the housing 102 when the cover 120 is coupled to the housing 102. The engagement of the latch 144 with the retainer 146 prevents upward axial movement of the cover 120 relative to the housing 102. As the outer handle members 142 are moved inward toward the inner handle member 140, the latches 144 also move inward along direction 148 and disengage from the retainers 146 on the housing 102. A gap 125 is formed between the handle assembly 122 and the first end 106 of the housing 102 to allow a user to grasp the handle assembly 122 from underneath and pull in a substantially vertical direction along axis 118. Simultaneously, the user squeezes the outer handle members 142 inward along direction 148 to disengage latches 144 from retainers 146 to remove the cover 120 from the housing 102. When replacing the cover 120, a user can use handle assembly 122 to align ends 152 with grooves 150 and move cover 120 downward along axis 118 until ends 152 of the handle assembly 122 slide along and past angled surfaces 154 and latches 144 engage retainers 146 snapping the cover 120 into place on the housing 102.

The air cleaner 200 includes a filter element 224. The filter element 224 is disposed in the housing 202 and axially extends between first and second axial ends that are respectively adjacent to the first and second ends 206, 208 of the housing 202. The air filter element 224 includes filter media 234 arranged in a cylindrical manner with an inner surface 230 defining a clean air outlet channel 232. An annular dirty air inlet channel 228 is defined between the outer surface of the filter element 224 and the housing inner surface 226. A first end of the filter media 234 is fitted with a top endplate 236 and a second end of the filter media 234 is fitted with a bottom endplate 238. In some embodiments, urethane adhesive attaches the filter media 234 to the cover 220 and as such, forms and acts as the top endplate 236. In this way, when the cover 220 and filter element 224 are assembled with the housing 202, the urethane adhesive axially seals the cover 220 to the housing 202. In some embodiments, the filter media 234 is embedded directly into the top endplate 236. In some embodiments, the top endplate 236 of the filter element 224 engages with the housing inner surface 226 such that a radial seal is created between the filter element 224 and the housing 202. The filter element 224 is axially insertable into the housing 202 through the first end 206 when the first end 206 is in an open condition (e.g., cover 220 is decoupled and removed from the housing 202). In addition, when the first end 206 is in an open condition, a user can access and service the filter element 224.
At the first end 206, the housing 202 includes a top perimeter edge 207 and two axially extending walls 251. The walls 251 extend above the top perimeter edge 207 and each wall 251 is positioned substantially opposite each other relative to the longitudinal axis 218. Each wall 251 forms a retainer 250 configured to receive a latch 252 formed on a handle assembly 222 of the cover 220 as described further below.
Referring to
Each of the handle members 221 includes a latch 252. Each latch 252 is configured to engage with a retainer 250 formed in the housing 202 when the cover 220 is coupled to the housing 202. The engagement of the latch 252 with the retainer 250 prevents upward axial movement of the cover 220 relative to the housing 202. As the handle members 221 are moved inward toward the axis 218, the latches 252 also move inward along direction 248 and disengage from the retainers 250 on the housing 202. A gap 225 is formed between the handle assembly 222 and the first end 206 of the housing 202 to allow for the flex of the handle members 221 when a user grasps the cross-members 223. When the user squeezes the handle members 221 to disengage latches 252 from the retainers 250 and simultaneously moves the cover 220 upward along axis 218, the cover 220 is removed from the housing 202. When replacing the cover 220, a user can use handle assembly 222 to align the latches 252 with the retainers 250 and move cover 220 downward along axis 218 until the latches 252 engage with the retainers 250 snapping the cover 220 into place on the housing 202.

Each latch 352 is configured to engage with a retainer 350 formed in the housing 302 when the cover 320 is coupled to the housing 302. The engagement of the latch 352 with the retainer 350 prevents upward axial movement of the cover 320 relative to the housing 302. As the handle members 321 are moved inward toward the axis 318 about pivot 315, the latches 352 also move inward along direction 348 and disengage from the retainers 350 on the housing 302. A gap 325 is formed between the handle assembly 322 and the first end 306 of the housing 302 to allow for a user to grasp the cross-members 323. When the user squeezes the handle members 321 to disengage latches 352 from the retainers 350 and simultaneously moves the cover 320 upward along axis 318, the cover 320 is removed from the housing 302. When replacing the cover 320, a user can use handle assembly 322 to align the cover walls 356 with the housing walls 351 and therefore align latches 352 with the retainers 350 and move cover 320 downward along axis 318 until the latches 352 engage with the retainers 350 snapping the cover 320 into place on the housing 302.

A gap 1125 is formed between the handle assembly 1122 and the first end 1106 of the housing 1102 to allow a user to grasp the handle assembly 1122 from underneath and pull in a substantially vertical direction along axis 1118. Accordingly, a user can squeeze the flexible portion 1121 toward the axis 1118 to disengage the protrusion 1154 from the slot 1161 while simultaneously pulling upward on the handle assembly 1122 to remove the cover 1120 from the housing 1102. When replacing the cover 1120, a user can use handle assembly 1122 to align the protrusion 1154 with the slot 1161 and move cover 1120 downward along axis 1118 until the protrusion 1154 engages with the slot 1161, thereby snapping the cover 1120 into place on the housing 1102.
Using the covers, handle assemblies and filter housings discussed herein, a cover of an air cleaner can be decoupled from an air cleaner housing using only one hand. The coupling mechanisms described herein can double as latching mechanisms and handles making coupling and decoupling of the cover to and from a filter housing easier for a user. When removing a cover, the user can grasp the handle assembly and thus disengage latches on the cover from retainers on the filter housing using a single hand and no tools. In addition, no separate latch mechanisms are required for coupling and decoupling of the cover thereby reducing the manufacturing cost of such assemblies.
References herein to the positions of elements (e.g., “top,” “bottom,” “above,” “below,” etc.) are merely used to describe the orientation of various elements in the Figures. It should be noted that the orientation of various elements may differ according to other example embodiments, and that such variations are intended to be encompassed by the present disclosure. Further, the formation of a passage by one or more surfaces can comprise a wide variety of passage cross-sectional shapes, for example, passages having circular, rectangular, oval, etc. cross-sectional shapes.
As utilized herein, the term “substantially” and similar terms are intended to have a broad meaning in harmony with the common and accepted usage by those of ordinary skill in the art to which the subject matter of this disclosure pertains. It should be understood by those of skill in the art who review this disclosure that these terms are intended to allow a description of certain features described and claimed without restricting the scope of these features to the precise numerical ranges provided. Accordingly, these terms should be interpreted as indicating that insubstantial or inconsequential modifications or alterations of the subject matter described and claimed (e.g., within plus or minus five percent of a given angle or other value) are considered to be within the scope of the invention as recited in the appended claims. The term “approximately” when used with respect to values means plus or minus five percent of the associated value.
The terms “coupled” and the like as used herein mean the joining of two members directly or indirectly to one another. Such joining may be stationary (e.g., permanent) or moveable (e.g., removable or releasable). Such joining may be achieved with the two members or the two members and any additional intermediate members being integrally formed as a single unitary body with one another or with the two members or the two members and any additional intermediate members being attached to one another.
It is important to note that the construction and arrangement of the various example embodiments are illustrative only. Although only a few embodiments have been described in detail in this disclosure, those skilled in the art who review this disclosure will readily appreciate that many modifications to the flow structures are possible (e.g., variations in sizes, dimensions, structures, shapes and proportions of the various elements, values of parameters, mounting arrangements, use of materials, colors, orientations, etc.) without materially departing from the novel teachings and advantages of the subject matter described herein. For example, elements shown as integrally formed may be constructed of multiple parts or elements, the position of elements may be reversed or otherwise varied, and the nature or number of discrete elements or positions may be altered or varied. The order or sequence of any process or method steps may be varied or re-sequenced according to alternative embodiments. Additionally, features from particular embodiments may be combined with features from other embodiments as would be understood by one of ordinary skill in the art. Other substitutions, modifications, changes and omissions may also be made in the design, operating conditions and arrangement of the various example embodiments without departing from the scope of the present invention.
